Scenario
The desert can be brutal on a horse with no name.

Good thing your Ma packed you well for the trip to East Yahoo. You've got a rifle for the buzzards, a shotgun for the snakes, and pistols for the vicious prairie dogs. Good thing she packed you plenty of ammo too because it seems they all want to eat your horse and attack you in unison. It's hard to decide which to kill first, but you'd better get them all because you'll be next.

Ammo
10 Pistol, 10 Rifle, 4+ Shotgun

Starting Position
Standing behind horse with both hands on its butt, with two safely holstered pistols
Rifle safely staged on horse
Shotgun safely staged on horse; at least four rounds on your person.

Procedure
When ready, yell "Come on ya mangy curs! Come and get some!"

At the buzzer, engage pistol targets in a continuous Palindrome sweep, starting at either end (1-1-1-2-2-3-3-4-4-4 or 4-4-4-3-3-2-2-1-1-1).

Holster pistols and engage rifle targets in the same manner starting at either end.

Make rifle safe and engage shotgun targets until down.
